ILLINOIS, A CORPORATION 01F AUTOMATIC PIN-SETTING MACHINE.

Application filed October 22, 19M. Serial no. 868,028.

ing is a specification.

- This invention relates in general to machines for automatically setting pins upon a bowling alley and returning the balls to the players-position and more particularly to certain novel mechanism, devices, combinations and arrangements of parts'which may be incorporated in the machine, which forms the subject-matter of my application filed June 6, 1914, Serial No. 843,372.

Among the objects of my present invenarranging the pins upon and releasing them from the assembly shelf and a novel setter frame, and means for controlling the delivery of pins thereto, whereby the structure and mode of o eration of my device, as previously disclosed is materially simplified and improved.

Other objects and advantages of my invention will be apparent as 'it is better understood by reference to the following specification and the accompanying drawings in which Figure 1 is a plan view of the alley and the setter frame with the conveyer and supporting structure shown in motion along the line 11 of Fig. 2; Fig. 2 is a vertical section through a portion of the device showing the setter and distributer frames in elevation; Fig. 3 is a vertical section on a somewhat enlarged scale taken on the line 3 3. of Fig. 5; Fig. 4 is a rear elevation of the device; Fig. 5 is a plan view of the device with the setter frame omitted; Fig. 6 is a side elevation of a portion of the device taken from the left of Fig. 5; Fig. 7 is a detail in elevation of the controlling means for the assembly shelf as shown in Fig. 6.; Fig. 8 is a plan view of the structure shown in Fig. 7; Fig. 9 is a sectional detail of the assembly. shelf; Fig. 10 is a detached plan view of the distributer frame and the re' leasing means therefor; Fig. 11 is-a detail showing the operating finger for the distributer frame; Fig. 12 is a detail showing the latch for connecting-the operating finger with the distributer frame, and Fig. 13 1s a diagrammatic view of the various electric circuits.

In pin setting devices for bowling alle s two operations are essential. The first is t e new-set operation in which all pins remainmg on the alley are removed by a sweeper and a full set of pins is deposited upon the alley bed in their proper relative positions.

Patented July II, illlfi.

The second operation 1s the deadwood removal operation and involves the lifting of the standing pins from the alley, the

sweeping of any pins which have been overturned and of balls from the alley and the resetting of the lifted pins in their proper posltlons. In my application previously referred to I have disclosed a strue ludng a setter frame and a sweeper together with proper mechanism for conveying the pins to the setter frame and means for operating and timing the operation of the setter frame and sweeper, all controlled through electric circuits by proper circuit-closing means disposed adjacent the players end of the alley. 1

I have found that the operating and timing means for the setter frame and the sweeper, as disclosed in my previous application referred to, are entirely satisfactory 'fhe bed and gutters are of usual construction and the pit is'provided with a bottom loping from the alley bed and with sloping sides, the sides and bottom converging toward an aperture 4 in the rear wall of the structure below the usual pad 5. Rearwardly of the pit 3 is a suitable casing 6 on an a adapted to be operated by a sprocket 9 mounted on the main shaft 10 of t e machine, the shaft bein driven by the motor V which partially incloses a chain conve er 7 haviw flights 8 disposed at intervals t ereing tracks 11 are provided, whereby the conveyer 7 moves in a wide are adjacent the aperture 4. A padded shelf 12 is suspended from'suitable rods 13 mounted in the-supporting frame 14 and springs 15 embracing ture will be sufficiently clear without further description. The balls and pins as they rollfrom the alley 1 or are removed therefrom by the sweeperpass into the pit 3 and roll down the sloping sides and bottom thereof through the aperture 4 into-the bottom of the conveyer where they are individually picked up b' the flights 8.

Duringthe upwar movement of the conveyer 7 the balls'leave the conveyer through an opening in the side of the casing 6, which is too small to allow the pins to pass therethrough, and return to t e players end of the alley along the track 16. The pins are carried by the conveyer 7 to the top of the casing 6 and fall therefrom into a trough 17 with their butt ends foremost. The means for preventing the pins from leaving the conveyer otherwise than as stated forms no part of the present invention, such means being fully dlsclosed in my application previously referred to, and it appears sufiicient for the presentdescription to state that such means, involving among other things the specific form'of the flights 8, is provided in my present structure.

The pins slide by gravity down the trough 17 until they engage a member 18 vpivotally mounted on a rod 19 from a bracket20 which is connected to and supported by the frame of the machine.

' The member 18 is'provided with an extension 21 (Fig. 8) havinga nose adapted to engage with and actuate a pawl 22 pivotally mounted on abolt 23 in a swinging arm 24 which is in turn pivotally mounted on the stub shaft 25 supported'by the frame. The

' The main shaft 10 which is driven through' suitablemeehanism/fro m the motor (not shown) is provided with aibevel gear 29 which meshes with a bevel pinion 29 (Fig.

6) on the stub shaft 30 mounted in the bracket 20.. A crank disk 31 is fixed to the stub shaft 30 and adapted to be driven (Fig. 7) suspended thereby and a link 32 connects the crank disk with the bolt 23 whereby the arm 24 andthe pawl 22 are swung about the stub shaft 25 when the main shaft 28 is in motion. Fixedto the stubshaft 25 is a ratchet disk 33 having a plurality of ratchet teeth 34, four being preferably provided in the I present instance, adapted to be engaged by the pawl 22-when the latter is moved into engagement therewith by the extension 21, whereby the ratchet disk 33 is actuated. A gear 35 is fixed to the stub shaft 25 adjacent the ratchet disk 33 and meshes with a pinion 36 fixed to the conveyer shaft 37. The ratio between the gear 35 and inion 36 is 4 to 1, so thatv upon each actuation of the ratchet disk 33 moving the gear 35 through one fourth of a revolution, the pinion 36 and the shaft 37 will make a complete revolution.

A disk 38 is secured to the shaft3'7 adslidably mounted in the end thereof on a shank 42 connected with a member 43 provided with a slot 44' which slidably engages an extension of the shaft 37. A spring 46 connected to the bracket 40 and the member 43 normally holds the saddle 41 in its rearmost position. At its forward end the member 43 is provided witha pin 47 which is positioned to be engaged by a nose 48 of a lever 49 pivotally mounted on the stub shaft 25 and connected through a spring 50 with an arm 51 securely mounted on the swinging arm 24. As the arm 24 is moved about its pivot by the link 32 during the operation of the machine the nose 48 Wlll engage the pin 47 and move the member 43' forwardly to draw the saddle 41 into the path of the pin 39 on the disk 38. This provides a positive stop for the conveyer shaft andprevents the shaft from making more than a single revolution at each actuation thereof.

The ratchet disk 33 is provided with two oppositely disposed pins 52 and a starwheel 53 is mounted on a stub shaft 54 secured to the frame, the arms of the star- I -wheel 53 being disposed in position to be engaged byt e pins 52 on the disk 33.

Preferably five arms are provided on the' star wheel .53 and inasmuch as two pins 52 I are provided on the disk 33 it will be apparent that the star-wheel will be actuated twice during the complete revolution of the disk-33 or once for'every second movement.

thereof. The StflIrWhBBl-53 will accordingly make a complete revolution when the disk 33 has been actuated ten times and inasmuch as the pawl. 22 engages the disk 33 whenever a pin falls from the conveyer 7 into the chute 17 and against the member 18 it will be readily understood that when ten pins havebeen received by the chute the star-wheel 53 will have made a comtended for the first two rows may from any position on the assembly shelf,

'plete revolution. The star-wheel 53 is provided with a cam-nose 55 which engages at each complete revolution the end56' of a rod 57 slidably mounted in the frame and extending transversely thereof as shown in Fig. 5. The rod 57 operates a latch 58 to release the assemblyshelf and allow the pins to fall into the chutes leading to the distributer frame. A spiral conveyer 58 is secured to the shaft 37 and revolves therewith. The conveyor 58 extends into an opening 59 (Fig. 5) in the chute 17 into the path of the pins (see Fig. 4) and is adapted to receive the pins as they fall in the chute 17, the heads of the pins resting on the conveyer 58 and the bases thereof against the member 18 and upon which each actuation of the ratchet disk 33 a pin is moved a distance equivalent. to its width transversely of the machine onto and along the assembly shelf 59, it being understood that when the member 18 is depressed by the Weight of a pin it alines with the retaining wall 62. p

The assembly shelf 59 comprises'a supporting frame pivotally mounted at 60 in the frame of the machine and normally held in the position indicated in Fig. 9 by a spring 61 secured thereto and to the frame of the machine. This spring is of suflicient strength .to move the shelf to normal position when empty but insufiicient to hold the shelf in this position when pins aredisposed thereon. A latch 58, previously described, is provided to hold the shelf in normal position until released. A retaining wall 62- (Fig. 5) is provided at the front'of the assembly shelf 59 and prevents'the pins from moving into the chutes 63 until the latch 58 has been released by the-mechanism previously described. In order that the chutes 64, which convey the pins to the first two rows,.may be disposed at a sulficient angle it is necessary that the pins corresponding preferably to the third, sixth and eighth positions be held in the position taken by the pins when the assembly shelf is in normal position while the remaining pins drop into the chutes 63. For this purpose I provide the supports 65 rigidly mounted in the frame and disposed through openings in the assembly shelf as indicated in Figs. 5 and 9. These supports 65 are disposed'beneath the butt ends of the pins and gates 66 are mounted on arms 67 con-. nected to the assembly shelf 59- and are adapted to drop therewith and allowthe pins to pass into the chutes 64. It is to be understood, of course, that the ins ine taken the positions indicated being merely those which have been found entirely satisfactory inthe practical operation of the machine.

The pins after being released from the assembly shelf as described slide down the chutes 63 and 64 and rest upon the distributer frame in their proper relative playing positions. The distributer frame comprises a plurality of fixed longitudinally extending members 67 secured to the frame of the machine and a movable frame comprising 'proper intervals to allow the. pins to fall into the setter frame.

The mechanism for moving the members 69 comprises a bellcrank lever 72 mounted on a bracket 73 secured to the frame of the machine. One arm of the bell-crank lever 72 is connected to one of the members 69 and a spring 73, secured to the bell-crank lever 7 2'and to the frame, normally holds this arm of the bell crank lever 72 in forward position so that the members 69 are disposed in their normal position to engage and hold the pins as they descendfrom the chutes 63 and 64. The other armof the bell-crank lever 72 is connected with a slidable member 74 supported in the frame of the machine and a latch 75 is pivotally mounted on the member tit 74 and adapted to be engaged by a finger 76 of a lever 77 which is connected by a link 78 to an eccentric (not shown) on the main shaft 28 of the machine. The finger 7 6 on the lever 77 is reciprocated as the shaft 28 revolves.

The latch ,75 is connected to the sliding member 74 by means of a spring 79 which tends to move it into position to be engaged by the finger 7 6, a pin 80 being mounted on the member 74 and disposed in a slot 81 of the latch 75 to limit the movement thereof. The latch 75 is normally held out of engagement with the finger 76 by means of a member 82 slidably mounted in a guide 83 and disposed between the end of the latch 75 and a stop 84 secured to the sliding member 74. The member 82 is provided at its op- .posite end with an armature 85 disposed within the solenoid coil 86 which coil, when energized, draws the armature forwardly to release the latch 75. A spring 87 con-. .nects the member 82 with its guide 83 and let I engage the end of the latch 75, forcing it v out of engagement with the. finger 76 whereupon the sprin 87 will force the member 82 between the atch 75 of the stop 84.

From the foregoing description it is thought that the Operation of this portion 9 a of the device will be apparent without further description. The finger 76 .is con-i stantly reciprocated when the machine is in operation and when the solenoid 86 is energized, withdrawing the member'82, the latch 75 will be released and will move into position to be actuated by the finger 76. The

' hers 68. and 69 rearwardly of the machine,

- closed having been found to be entirely satwhereby the pins which are resting thereon will be released and will fall. into the setter frame mechanism. 7

- The setter frame comprises a frame work composed of angle irons90 preferably ar-- ranged in triangular form, as shown in Fig.

1, upon which are supported the transverse members 91 supporting the magnet coils 92 which are loosely suspended in said membersby means of bolts 93, whereby a small amount 'of-the vertical play is allowed when the magnets descend and engage the tops of the pins. The setter frame is preferablysuspended from its corners by means of chains 90 passing over suitable pulleys and attached to a counterweight, this mechanism not, however, being shown for-the reason that it is' fully disclosed in my application previously referred to, the structure disisfactory in the practical'use of the device. Atthe rear corners of the setter frame vertical members 94 (Fig. 2) are secured having at their upper extremities rollers 95 which engage the gate-cam plates 96 secured In the new-set operation the setter frameto the frame of the machine at either 'side thereof. Each gate-cam plate 96' is provided with two vertical slots 97 and two oblique. slots 98, sprin pivoted at, 99' being- 7 rther provided to lilmit the movement of'the-rollers 95 in the s ots.

two distinct movements of the setter frame.

descends until the bottom thereof nearly rests upon the alley floor whereas in the deadwood-removal operation the frame descends merely until the magnet coils 92 contact with the tops of the pins. standing on the alley. The setter frame is actuated to ca out the movements indicated through uitable connections with an operating and timing mechanism, previously referred to as not shown the present application and the gateacam plates 96- are provided to guide the movements of the setat the right of Fig. 9 and thence upward .in the deadwood-removal operation.

actuated gates 99 setter 97 until the setter frame is disposed adjacent the alley bed. Upon'the upward movement of the setter frame'the gates 99 prevent the entrance of'the rollers 95 into the lower oblique slots 98 and hence the rollers pass upward in the vertical slots 97 at the left in Fig.2

into the upward oblique slots 98 and through the upper gates 99 Into the vertical slots 97 to the normal position of the setter rame.

In the deadwood-removal "operation the rollers 95 descend merely in the verticalslots 97 at the rightin Fig. 2 which are of suflicient length to allow the magnet coils 92 to engage the tops of the pins and then move upwardly in the same slots without passing into the oblique slots. It will be readily understood that the gate-cam plates 96 allow the setter frame a combined vertical and forward, movement in the new set operation and a vertical movement oli illly e forward movement has for its object the placing of the pins in position directly beneath the normal. position of the magnet coils 92 when the setter frame is in its upper position in order that as the frame descends in the deadwood-removal operation the pins will-be disposed to'be-engaged and picked up by the magnet coils whlch are energized through suitable electrical connections and attract the iron cores 100 disposed in the heads of the pins.

Disposed beneath.the frame work composed of members 91 are longitudinally extending members 101 and 101'-having slots 92 engaging the supporting bolts 91'. Transverse members 102 and 103 are secured at intervals on I'nembers1101 and 101' respectively and carry the complementary sections 104, 105, respectively, forming cupshaped' members adapted tohold the pins,

. when disposed adjacent each other, as in- The operationv of the machine requires dica'ted in full lines in Fig. 2. The sections 104 and 105 are mounted directly behind the magnet coils 92 so that the pins carried therein will be deposited on the alley bed directly beneath the magnet coils, as previouslydescribed during the new-set operation. i

HPivotallymounted at 117 inthe bracket 106 on the setter frame is a bell-crank lever 107 having an arm 108 connected to a link 109 which extends throu h a stop 110 on the frame of the-machine. T 112 are mounted on the link 109 and are adapted to contact with the sto the setter frame reaches either o its extreme wo abutments 111, i

110 when positions; The bell-crank lever- 107 is pro vided with two arms 113, 114, the arm 113 being connected by means of a link 115 to the real-most transverse member 102 while the arm 114 is connected by a link 116 to 1 cated in full lines in Fig. 2 the abutment 112 will have engaged the stop 110 as indicated and the bell-crank lever 107 will be turned to draw the members 102 and 103 and hence the sections 104 and 105 together, whereby these members will form a cup for the reception of the pins in upright position. As the setter frame is lowered and guided by the gate-cam plates 96 to the position indicated in dotted lines in Fig. 2 the abutment 111 will engage the stop 110 and turn the bell-crank lever about its pivot 117, thereby moving the members 102 and 103 and hence the sections 104 and 105 in opposite-directions whereby the pins are released from the cups and upon the vertical movement of the setter frame guided by the vertical slots 97 at the left in F ig. 2 the pigs will be left standing upon the alley The circuits involved in the electrical con trol of my present invention are substantially identical with those disclosed in the prior application. I have, however, devised an improved switch-operating means for controlling the circuit of the solenoid coil 86. The switch comprises a base 120 of suitable insulating material secured to one of the longitudinal members 67 and provided with contact points 121 and 122. A contact arm 123 is pivotally mounted at 124 and a bell-crank lever 125 is secured to the contact arm 123 and comprises the operating means therefor. Upon one arm of the bell-crank lever 125 the finger 126 is pivotally mounted and normally held in the position indicated in Fig. 3 by a spring 127 attached thereto and to. the arm of the bellcrank lever. A rod 128 is secured to the setter frame and is provided at its upper extremity with a finger 129 which is adapt-.

ed, as the setter frame descends, to engage and pass the finger 126 without actuating the bell-crank lever 125. On the upward movement of "the setter frame, however, the finger 129 engages the finger 126 and inasmuch as the finger 126 is held from turning in this direction by a pin 130 on the bell-crank lever 125 the finger 129 will turn' the bell-crank lever 125 about its pivot and move the contact arm 123 to engage the contact 122. As will be later explained the circuit is thereby closed through the solenoid coil 86 which controls the operation, of

the distributer frame and it will be readily understood that since the contact arm 123 is actuated only after the setter frame has been lowered to deposit pins on the alley bed the distributor frame can only be actuated to supply pins to the setter frame when the latter is empty. Upon the forward movement of the transverse members matically shown in Fig. 13 in which 130.

and 131 indicate the source of current for operating the various devices; 132 indicates a blow-out coil for preventing sparking at the various contacts; 133 is a solenoid coil for operating the main clutch; 134 and 135 are solenoid coils controlling the timing mechanism for retarding the operation of tlie'sweeper or the setter frame, respectively, in the new-set and deadwood-removal operations; 136 and 137 are contact makers adapted to be disposed adjacent players end of the alley for controlling the machine; 138 is a safety device, including a "magnet coil, for preventing the starting of a new operation before the preceding one has been completed, and 139 is a contact maker adapted to be closed by the weight of the foremost pin in the distributer frame. All of the foregoing mechanism is fully described in my previously noted application. The solenoid coil for controlling the operation of the distributor frame is indicated at 86;

121 and 122 are the contact points and 123 the coiiperating contact arm.

When the new-set operation is desired the proper contact maker 137 is closed whereby the circuit is closed from the positive source of current 131 through blow-out solenoid 132 to the main clutch operating solenoid 133 which starts the operating of the machine; through solenoid 135 of the timingmechanism to retard the operation of the setter frame until the sweeper has been actuated to clear the alley of pins, etc.; through contact maker 137, contact point 121, contact arm 123, and thence back to the nega untilthe standing pins have been lifted from tau - to the setter frame only when the latter is empty and a full complement of pins is held in the distributer frame will now be described. The solenoid 86 and the circuit closing means comprising the contact point 122; and the contact arm 123 has previously been described." The contact arm 123 is actuated to close the circuit only after the setter frame has moved to its lowermostposition to depositpins and is'hence empty.

-- A contact maker 139 is disposed in the dis- "the weight'of the foremost tributer. frame in position tobe closed by in of the set. resting thereon. It will there ore be readily understood that when a-set of pins is. held in the distributer frame and the setter v frame ascends after depositing its pins the circuit will be closed from the positive source of current 131 through the solenoid 86' which controls the mechanism for supplying pins to the setter frame, through conftact maker 139,- contact point 122, contact arm 123, and thence to the negative source of current 130. The circuit is broken by the return of. the members 69, which hold the pins in the distributer frame, to normal position through the finger 69 as has prev standin bed durmg the deadwood-removal operation '36 viously been described.

The'circuits and contact mechanism'for controlhng the magnet coils 92 whereby the pins are removed from the alley and whereby any particular combination of pins may be selected from a set and lifted 'froni the bed while the-remaining pins are swept from the alley bed, are identical with those disclosed in my application previously referred to and form no part of my present invention. Hence the contact mechanism and circuits are not specifically described in Y the present application.

It is thought that my invention will be readily understood from ,the'foregoing and "Iclaim:

it will be obvious that various changes may be made 1n the devices, mechanisms and circuits described without departing'from the spirit and scope of the invention or sacrig5- ficing any of its material advantages, the
